Dr. Sanders
By the end of today's class, you should be able to do the following:
w Review: Just how thick is the
crust? mantle? core?
w Describe the differences between the two kinds of
crust in terms of thickness, density and overall color of the major kind of rock
that occurs there, and where on Earth the two types of crust occur.
w Draw a to-scale
diagram illustrating the internal structure of the Earth, including crust,
mantle, and core.
w Review: How did the Analysts and Peer
Reviewers do at identifying geotectonic patterns? ("Teams will earn one point for
each valid and supportable pattern they come up with, and Peer Reviewers will
earn a half-point for each one they review correctly and pass to the instructor.
Total possible points: 7.5.")
w Explain the difference
between brittle deformation and ductile deformation.
w Describe the
characteristics of the lithosphere and asthenosphere.
w Sketch a diagram of
the internal structure of Earth illustrating the positions of the lithosphere
and asthenosphere.
w Describe the basic
principles of geotectonic theory.
w Examining a map of
geotectonic boundaries, add the information about boundary type to your collection of
information about our fourteen study sites.
